Claims (2)
- 차축과 프레임 사이에 공기스프링이 설치되는 에어 서스펜션에 있어서, 차축의 수직방향 압력을 검출하는 압력센서와, 상기 압력센서의 검출신호를 근거로 차량 상태를 차축의 기울기 및 각도를 연산처리하고 처리된 결과를 기설정된 데이터 테이블과 비교하여 해당 제어신호를 통해 각각의 공기스프링에 작용하는 공기압을 실시간으로 제어하는 ECU와, 상기 ECU의 제어신호에 따라 공기스프링에 작용하는 공기압을 조절하는 밸브가 구비된 공압파이프로 구성됨을 특징으로 하는 에어 서스펜션 제어장치.
- 제1항에 있어서, 상기 공압파이프에 해당 공기스프링에 작용하는 공기압을 조절하기 위해 에어 서플라이밸브, 2방향밸브, 레벨링밸브, 3방향밸브가 순차적으로 설치됨을 특징으로 하는 에어 서스펜션 제어장치.
